BOB: Watts are not the measure of carbon rod success. You need to obtain a transformer with low voltage, around 6v., preferably with a half-tap to 3v. for fine work, and 20 amps. The amps are the key. That combination will get you where you want to go. Gerry Evans In St. Louis

While it worked using a pencil lead with an AF 50-Watt transformer, the 50-Watts was not powerful enough to make it work with a carbon welding rod. Over the weekend, I picked up a dual throttle AF 18B 175-Watt transformer, which I assume works out to 87.5-Watts for each throttle. While it appears to be capable of doing the job, all it really does is trip the circuit breaker. Two questions: 1. - Can I connect the two sides in parallel for more power and less strain on the circuit breakers? 2. - What else am I doing wrong?
